Description

The present invention relates to a wheelchair turntable.

Conventionally, as a wheelchair turntable, for example, there is a home elevator provided with a turntable disclosed in Japanese Patent Application Laid-Open No. 2002-120984. The home elevator equipped with this turntable is a facility that is provided with a turntable portion on a residential elevator floor and is attached to the residential elevator.

According to the present invention, a conventional wheelchair user turns in a confined place by his own wheelchair operation, and it is inconvenient to turn in a restroom, washroom, etc. of a house. From a consideration point of view, it is intended to provide a turntable for a wheelchair that can easily change the direction and reduce the burden on wheelchair users.

Means to solve the problem

In order to solve the above-mentioned problems, the configuration of the present invention includes a safety brake mechanism that has a support shaft on the lower surface of a turntable, is rotated by a drive motor, and is stopped and fixed at a free position by a switch and / or remote operation. It is the turntable for wheelchairs characterized by having.

It is equipped with a turntable floor installation height adjustment mechanism and can be used by being fitted into the building floor.

The turntable for mobile wheelchairs is equipped with a drive motor on the floor adjacent to the turntable to hold the height from the floor and make it easy to get on and off the wheelchair, and the slope can be fixed or movable in each direction. It is also possible to get on and off.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings and reference numerals. 1 is a plan view showing an example of a turntable for a wheelchair of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, FIG. 3 is a plan view of another example of the turntable for a wheelchair of the present invention, and FIG. FIG. 3 is a cross-sectional view taken along line BB in FIG.

1 and 2, 1A has a slope 6 on one side and a caster 7 on the other side, and a base plate that has a flat quadrangle made of a double plate formed at a low height, and 1 is the center of the base plate 1A. It is a turntable loosely fitted in a round hole 1a formed in the part, and is attached to the base plate 1A by a shaft 4 so that its upper surface is substantially flush with the upper surface of the base plate 1A. Reference numeral 3 denotes a drive source provided at a corner of the upper surface of the base plate 1A. Here, a motor is used, and its rotational output is transmitted to a turntable by a belt, a chain, or a drive pulley. Reference numeral 2 denotes a mark for positioning the wheelchair wheel formed on the upper surface of the turntable 1, and constitutes a safer wheelchair turntable. The slope 6 can be attached to one side or a plurality of sides and can be fixed or removable.

3 and 4, 1B is a building floor having a substantially circular opening 1b for loosely fitting the turntable, 1 is a turntable loosely fitted in the opening 1b of the building floor 1B, and the upper surface thereof is the building floor 1B. It is attached to the building structure 9 via a height adjusting mechanism 5 so as to be rotatable by a shaft 4 so as to be substantially the same surface as the upper surface. Reference numeral 3 denotes a drive source provided on the lower surface of the turntable 1 and the upper part of the building structure. Here, a motor is used, and the rotation output is transmitted to the turntable by a rack and pinion mechanism or the like.

Of course, the shape and material of the wheelchair turntable in the present invention are not limited to those described above.

The invention's effect

When the wheelchair turntable of the present invention is installed on a concrete floor, a wooden floor or the like in a confined place such as a toilet, washroom, corridor, etc., the wheelchair is stopped at a safe display stop position, and a switch and / or By turning and stopping with the remote controller, the burden on the wheelchair user can be reduced, and even in places where the space for turning cannot be secured, the wheelchair user's movement etc. The burden is reduced. Moreover, since a space for turning a wheelchair is not necessary, it is possible to provide a margin for the floor plan.

If a mobile wheelchair turntable is used in an existing house, office, public facility, etc., it is unnecessary to renovate the building to secure a wheelchair turning space, which can be a useful tool.
